Statistical multiplexing

Okay kiddo, so let’s imagine you are playing with a toy truck and you have some friends who also want to play with it. But there’s only one truck, so you can’t all play with it at the same time, right? That’s kind of like how a bunch of people want to use the internet at once, but there’s only so much space on the network for all their data to travel.

Now, imagine you and your friends are taking turns playing with the truck. You play with it for a little bit, then you give it to your friend to play with, and then they give it back to you. See how that works? That’s sort of like what happens with statistical multiplexing.

You see, when lots of people want to send data across the internet, they can’t all send it at once without causing a big traffic jam. But statistical multiplexing lets them share the space on the network by taking turns.

So, let’s say you’re watching a video on the internet. It needs to be broken up into lots of tiny pieces called packets, which travel across the network to get to your computer or phone. When lots of people are trying to watch videos at the same time, there might not be enough space on the network for all those packets to travel across without bumping into each other.

That’s where statistical multiplexing comes in. Instead of trying to send all the packets at once, the internet looks at how much data each person is sending and waiting. If someone isn’t sending any data right now, their space on the network can be used by someone else who has more data to send. This means that everyone gets a turn to send their data, but the network isn’t overwhelmed with traffic all at once.

So, just like how you and your friends take turns playing with the toy truck, statistical multiplexing helps lots of different people share the internet and all their data without getting in each other’s way too much. Cool, huh?
